Abstract The magnetic after-effect of hydrogen-charged iron was investigated in the temperature range between 77 and 200 K. The hydrogen cold-work peak, known so far only from internal friction measurements, has been observed at about 130 K together with a less pronounced relaxation peak at 80 K. The activation energy of ∼0.29 eV, determined for the cold-work peak, is explained by a thermally activated motion of dislocations, the cores of which are closely decorated by a condensed atmosphere of hydrogen atoms.
